300ex and 250x bore

[ericstam07]

will the jug on a 300ex bolt up on a 250x because i was thinking of gettin a 300ex jug and a weisco piston for my 250x will this work?

Why would you want to get a 300EX jug? The piston is the exact same size, so it won't give you a "big bore".

how is that? the 300ex has about 292cc and the 250x has about 248 or somewhere around there

what i was thinkging of doing is gettin a 300ex jug with 300ex sleeve so it is like me having 292cc like a 300ex or maybee even gettin the 300ex sleeve about .060 bored. if the jug will match up with the 250x motor

There's more to displacement than bore size. The 300EX has a longer stroke than the 250X.

If you want more power, it's very simple. Do a web search, there are LOTS of racing companies that make kits and offer machine services. Almost any place that lists 300EX kits will also have a 250X kit for the same price, but you may have to call to get full details.

Do a little research on it, then get back to us with questions.

a 300ex only has 282cc's
